"Old Flames Can't Hold a Candle to You" is a country song written by singer-songwriter Patricia Rose Sebert and Hugh Moffatt. It was a number 14 U.S. country hit for Joe Sun in 1978, and a number 86 hit for Brian Collins the same year. It was later covered by Dolly Parton, who took it to the top of the U.S. country singles charts in August 1980. In the song, the narrator tells their lover not to feel threatened by past affairs for these "old flames" are in the past. Parton included her version on her 1980 Dolly, Dolly, Dolly album, and it was released as the album's second single after the success of "Starting Over Again". In 2013, Sebert's daughter, Kesha, released an acoustic cover of the song as part of her extended play Deconstructed.
